Maths by Month – April

In this April overview for Operation Maths users, there are links to topic-specific posts and articles, as well as a whole host of extra suggestions, links etc. To ensure you don’t miss out on any future Maths by Month blog-posts, please subscribe to the blog via email, on the top right hand of this page.

Pssst! There is still time to register for the April Edco Primary Publications launches for 2018 , which will be taking place in Kilkenny (rescheduled because of the snow), Galway, Athlone and Wexford. As well as launching Number Facts 1-4 and Bua na Cainte 3, they will also be showcasing Operation Maths and Exploring Spelling. Click on the link above for more info and to register. If you want to find out more about the Number Fact series you can read this comprehensive and independent review from the Irish Primary Teacher blog and/or you can check out the Number Facts site.

Operation Maths Jr Infs to 2nd classes:

Junior Infants will be exploring ordinal number (first, last), comparing and ordering numbers 1-5, as well as combining sets of numbers to 5. As usual, a whole suite of supporting activities are detailed in the TRB as well as ideas for Aistear play.

Senior Infants will be consolidating their understanding of the numbers to 10, via counting and numeration and the combining and partitioning of sets using a variety of models including the Operation Maths ten frames. As mentioned previously, the Number Talks resources for the numbers to 10 available at the link are very applicable as well as the practical activities and stations using concrete materials, that are suggested in the TRB. Extra resources that could also be used to consolidate these concepts include the Splat! resources made freely available here by Steve Wyborney. This link will bring you to his Splat! resources for the numbers 3 to 10, which are ideal for senior infants at this stage of the year. Play the PowerPoint presentations on your class IWB while the children use their Operation Maths MWBs to respond.

Senior Infants will also be exploring the strand unit of capacity toward the end of the month.

First Classes will be looking at Time and 2D shapes. This work will largely centre around half and halves, (eg time to half hours and partitioning shapes into halves) as introduced formally in the strand unit of Fractions in March

Towards the end of the month, in Operations, the children will be exploring addition and subtraction without renaming. This is an extension of the activities completed in March as the operations are now up to the first class limit of 99.

As mentioned in Maths by Month in March, on many of the pages in the At School books the calculations are presented horizontally. This is deliberately done to encourage the children to complete the calculations using concrete materials, pictorial representations and/or mental strategies, as opposed to always using the vertical column method. While the development of traditional written procedures (eg the column method) is still important, these written methods are not more important than the development of mental computation skills and the ability to visualise and manipulate numbers mentally.

Some of the mental strategies for addition and subtraction, used in Number Talks, would also be every useful here e.g. partitioning, friendly numbers, making tens (compensation) and removal (deduction). Suitable number strings can be accessed at the link above and of course teachers can make their own number strings based on the horizontal calculations in their At School book, for example, from page 93 (four calculations in each number string works well) : 39 – 7, 39 – 0, 39 – 1, 39 – 9

Second Classes will exploring 2D shapes, Capacity and 3D shapes and angles. Angles are introduced for the first time in 2nd class, and the concept is linked closely to the children’s understanding of fractions, spatial awareness and 2D shapes.
